To all whom it may concern.- friction ring of the clutch attached at oneend,

Be it known that I, GEORGE PHILION, of requires lathes of special formand costly Mishawaka, in St. Joseph county, in the'State make, and thisenhances the cost of construc- 5 of Indiana, have invented new anduseful Imtion. To obviate these difficulties, I have 5 provements inFriction-Clutches; and I do constructed the hub separate from theclutch,

E is one half a split pulley, in position on the hub D.

When used as a cut-off coupling, the hub, Fig. 3, is used. It is notnecessary that the hub should be split, because it is sometimes placedat the end of the shaft. I prefer, however, to split it part way, asshown at s in Figs. 3 and 4. The clamp bolts 3' will then serve tocompress the hub upon the shaft sufficiently to receive strongfrictional contact.

In constructing the clutches, the center hub seat 9 is bored to somestandard diameter and the hub flanges m and ends 'i are all turned tothe same standard, and can be in- The center bore of the hub must beproper for the shaft upon which it is to be placed, and when to carry apulley the length and exterior diameterof the hub must adapt it to saidpulley. The hub and friction member 0 are secured together by means ofbolts 76 whereof the heads are concealed within the member 0, and thenuts are on the outside. By this means, when it becomes necessary tore-babbitt the hub it may be removed from the shaft and from the clutchby removal of the nuts 7c and replaced as easily. This is a convenienceof considerable importance as it obviates labor necessary in taking theclutch apart, and does not disturb any of its adjustments.

The pulley E may sometimes be used as a driving pulley and the part Gwill then be the running part, and the part B and shaftA will bestanding parts, but this change will not involve any variation whateverin the structure or mode of operation of the several parts of thedevice. When used for a cutoff coupling both parts are rigidly securedto their respective parts A A of the shaft.

Having described my invention, I claim as new- 1. In a clutch thecombination of a clutch member having the hub seat g bored to a standardsize, the hub made separate from said clutch member and provided withthe cylindrical end or shoulder '6 formed of a size to fit said seat,having the flange m and formed at its end beyond said flange with thecylindrical sleeve, substantially as set forth.

2. In a clutch, adapted to be used as a shaft coupling, the combinationof the clutch member provided with the hub seat 9 bored to a standardsize, and the hub provided with the shoulder or bearing 1' formed of adiameter to fit said seat, having the flange m,and beyond said flangewith the split sleeve adapted to be compressed upon the end of theshaft, substantially as set forth.
